Paragraph 0069; 0073-0074, (2019/08/20)
The invention discloses a blue organic luminescent material, a luminescent device and a preparation method. The molecular structural formula of the blue organic luminescent material is as follows in the description, wherein D is 1,3-diphenylamine benzene, A is a nitrogen-containing heteroaromatic ring and n is equal to 1-4. The nitrogen-containing heteroaromatic ring has excellent stability and strong electron-withdrawing ability and has carrier transport capacity close to that of 1,3-diphenylamine benzene, and balanced carrier transport capacity is conducive to improving luminous efficiency.Besides, the benzene chain is selected for L, the number of benzene is 1-4, the molecular weight is 1000 or lower, and synthesis is easier.
